| dc.description.abstract | Penggunaan smartphone menghasilkan radiasi panas dan elektromagnetik yang berbahaya, sehingga diperlukan pelindung untuk mengurangi efek tersebut. Tanaman lidah mertua (Sansevieria trifasciata) diketahui dapat menurunkan radiasi elektromagnetik pada beberapa peranti elektronik. Penelitian ini bertujuan menetapkan formula film PVA-ekstrak terbaik dari lidah mertua untuk pelindung smartphone yang menurunkan efek radiasi secara optimal. Formula film dibuat dengan meragamkan volume akhir film, nisbah PVA: ekstrak, serta konsentrasi ekstrak. Radiasi panas diuji dengan PASCO CI-6505B dan radiasi elektromagnetik dengan GM-3120. Ekstrak terbaik dari uji radiasi adalah ekstrak aseton dalam volume film 100 mL. Nisbah terbaik dihasilkan oleh film dengan rasio PVA:ekstrak aseton 1:2, dan konsentrasi aseton terbaik, ialah 5%. | id |
| dc.description.abstract | Smartphone produce harmful heat and electromagnetic radiation that need protection to reduce their effects. Sansevieria trifasciata is known to lower electromagnetic radiation on some electronic equipment. The study aimed to determine the best formula for PVA-extract of S. trifasciata that optimally lowers the effects of radiation. The films were prepared with various formulas by varying the final volume of the film, the ratio of PVA:extract and the concentration of the extract. Heat radiation was tested with PASCO CI-6505B and electromagnetic radiation with GM-3120. The best extract from the radiation test is acetone extract in a film volume of 100 mL. The best ratio produced by the film with the ratio of PVA:acetone extract is 1:2 and the best acetone concentration is 5%. | id |
